HEEL-ATTAGHING, MACHINE.

Specification of Letters Patent.

Patented Mar. 30, 19115..

Application filed February 12, 1908. Serial No. 415,543.

To all whom it may concern:

Be it known that I, CHARLES A. POTTER, a citizen of the United States, residing at Lakeport, in the county of Belknap and State of New Hampshire, have invented certain Improvements in I-Ieel-Attaching Ma chines, of which the following descriptlon, in connection with the accompanying drawings, is a specification, like reference charaoters on the drawings indicating like parts in the several figures.

This invention relates to heel attachlng machines.

' In heel attaching machines such as are now commonly used in the manufacture of boots and shoes the attaching nails are brought by a movable nail carrier into position to be driven. The nail carrier is actuated by hand and is supplied with nails at a point removed from the nail drlvmg mechanism.

The primary-object of the present invention is to provide a heel attaching machine with means for automatically supplying nails to a nail driving mechanism.

A further object of the invention is to provide a heel attaching machine with nail supplying means which shall not require to be separately actuated by the operator.

In carrying out the invention, I prefer to employ means for bringing nails into position to be driven arranged to be automatically actuated independently of the mechanism for driving said nails. The provision of actuating means independent of the driving mechanism for bringing nails 1nto .position to be driven permits the operation of the nail supplying mechanism to be more conveniently timed than is possiblewhere a nail supplying mechanism and nail driving mechanism are operated interdependently.

In order to dispense with the necessity of separately actuating the nail supplying mechanism, a further feature of the invention consists in arranging this mechanism for actuation by a part of the machine which is manually controlled by the operator. .According to this part of the invention,

the nail supplying mechanism is controlled by the movement by the operator of the to the nail driving mechanism.

The machine to which the present invention is shown applied includes a nail block provided with nail receiving passages and With drivers arranged to be automatically reciprocated in said passage to drive the nails, into the heel. A shoe support is arranged t'or movement b the operator into and out of the range of the nail driving mechanism in order to facilitate the applir catlon and removal of the shoe.

n important feature of the present invention consists in the provision of means for supplying nails to the nail driving mechanism arranged to be brought into action by the movement of the shoe support, and preferably by its movement out of the range of said nail driving mechanism. With this arrangement the necessity of giving the nail supplying mechanism separate attention is avoided, the supply of nails to said mechanism being efl'ected by an operation incident to removing a heeled shoe from the machine. The construction is preferably such that the nail supplying means is not brought into action until near the end of the outward movement of the shoe support. This is of advantage in that it permits such slight movement of the shoe support as may be required in properly adjusting upon the support the shoe to be heeled, Without actuating the nail supplying device.

In the particular embodiment of the invention herein shown and described, a nail carrier is arranged for movement from a nail receiving position into a nail delivering position over the nail block. Means are provided for automatically reciprocating the nail carrier between said positions, said means being brought into action by the movement of the shoe support into inoperative position. Said means is arranged for operation independently of the mechanism for driving the attachingnails, so that it may operate prior to the actuation of said mechanism. In order to insure that the nails shall have time to fall from the nail carrier into the nail block before the former is returned to nail receiving position, the means for reciprocating the nail carrier is constructed to maintain the nail carrier with its nail holes in registry with the-nail passages in the nail block for a short interval of time.

Other features of the invention Will be hereinafter described and defined in the claims.

In the drawings,-Figure 1 is a view 'n perspective of a portion of aheel attaching machine embodying the present invention;

' F is view in side elevation with parts in vertical section of the nail carrier actusting mechanism shown in'Fig. 1.

The present embodiment of the invention is shown applied to a machine having the construction of that shown in United States Letters Patent, No. 884,513, granted to Benjamin F. Mayo April it, 1908. It will he understood however,that the invention may he applied to machines of different construction from that shown in said patent.

Referring to the drawings, the machine illustrated comprises a shoe support or jack 2 pivotally sustained at 3 by anadjustable supporting device. A spindle 4 is arranged for movement in a vertical guideway upon the frame of the machine and is reciprocated by automatic actuating means under the control of the operator. A head 65, carrying drivers '8, is secured to the upper end of the spindle 4:. The head 6 carries uides 10 mounted on o posite sides thereoi and sus 'tained inthe ower ends of said guides are springs 12, said springs receiving through them reduced portions of rods 14 arranged toslide in hearings on the head 6, the lower portions or the rods being extended through the guides 10. Said springs 12 have engagement at their upper ends with shoulders upon the rods I l. Secured to the upper ends of the rods 14 is a nail block head car rying a nail block 16 provided with driver passages to receive the drivers 8.

As will appear from the patent above referred to, in the operation of the machine containing the parts above specifically referred to, as the spindle iis lifted the driver head and nail block 16 rise in unison until the upper side of the heel. is pressed into engagement with the heel seat of the shoe sustainedby the shoe support 2. After the pressure of the nail block on the heel has reached a predetermined amount, measured by the springs 12, the nail block is arrested,-

.rier arm 24 provided with a nail carrier 25 is pivotally mounted upon the rod 18, said nail carrier being arranged to swing over the nail block and deliver nails thereto. A combined heel holder and top lift holder 26 is pivotally mounted upon'the upper surface of the nail block head and is actuated in the manner described in the patent above referred to. Saidholder is provided upon its under side with a roller 28 which is engaged by a member 30 upon the nail carrierarru to swing said holder into the position shown in .Fig. 1 in which the heel holder registers "spring not shown is provided to move the holder to bring the top lift holder into aline ment with the nail block, the latch 32 being automatically released to permit this movement in the downward movement of the head alter the heel attaching nails have been driven; all as is described more in detail in the patent above referred to.

At the rear of the rod 18 which sustains the nail carrier is arranged a stud 38 secured to the fixed frame of the machine. Upon the lower end of the stud 36 is rotatably mounted a driven member 38. Mounted for rotary movement upon the stud 36 above the driven member 38 is a driving member d0 which has upon its upper side a bevel gear 42. Said bevel gear 42 is engaged by a similar gear 44: secured to a horizontal shaft 46 which is continuously rotated in a suitable bearing by a pulley 4:8, driven from any convenient source.

The driven member 38 is provided with a vertical socket near its periphery in which is arranged a plunger 50 provided with a conical head and pressed yieldingly upwardly by a spring 52. The driving member is provided with a plurality of conical recesses 54 arranged to be entered by the conical head of the plunger 59. The plunger is provided with a pin 56 extending laterally therefrom. Pivotally mounted at 38 upon a projection carried-by the rod 18- IS a lever 60, the outer end of which is wedgeshaped hnd provided with a semicircular recess 62 at the rear of the wedge shaped portion. As will appear from Fig. 2 the lever is arranged tolie between the pin 56 and a flange rm-med upon the upper end of the driven member 38. A spring 63 is provided to press the lever 60 againstthe driven member In this position of the'lerer so the plunger 50 is held in inoperative position out of engagement with the driving noenr ber 40. When the lever 60 is moved outwardly away from the driven member 38 the plunger 50 enters one of the holes in the driving member and thus causes the movement of the driving member to be imparted to the driven member.

It will be understood that there is no novelty in the clutch mechanism per 66 above specifically described, and that other clutch mechanisms could be substituted for that shown without departing from the present invention. 4

The driven member provided 'at its lower side with a wrist pin d l te which is 76 which Works in a issuers Outward movement of 66 is limited by a stop slot formed in the tueredby a pin 68.

pin 68 in the rod bular portion of said rod 66. A spring 72 holds the pin 68 in its .a single revolution to e driven member'38 which is provided-With a its forward end adapted to pass over a pin its outermost position. The pin 68 is pivotally connected to a projection 74 upon the nail carrier arm. It l be seen that in a revolution of the riven member 38 the nail carrier will be swung over thenail blmkand thereafter returned to its original position.

To eiiect the actuation of the clutch con- .T

trolling lever 60, there is provided a triplever 76 pivotally mounted at $8 upon e clamp bracket sustaining device sup ted by the rod 18. lever ?6 carries a dog 80 pivoted at 82 and held yieldingly against the side of thelevcr by a spring 84. The dog 80 is arranged to engage the inner end of the lever'60 in the rearward movement of said dog and move lever 60 out of engagement with the pin As the lever 60 moves away from the pin 56, the dog'80 .passes'by its inner end and the lever '60 is thus allowed to be returned by the spring 63 into engagement with the side of the driven member 38. In

this position it is engaged bythe pin 56 at end of a revolution-of the'driven member and by its engagement with the said depresses the plunger out of opertive relation to the driving member 40. is positively arrested e end ofthe revolution by the recess 62 Aer. .ed inthe lever 60, said recess being entered by. the pin 56. It will be understood that in the forward movement of the outer thus allows this end of the-lever topass the inner end of the lever 60. The inner end of the tripping lever 7 6 is connected to the shoe support 2 by meansof a bar 86 l notch adjacent to carried by the shoe support. I have shown a manually actuated lever 90 for raising the bar. 86 out ofengagement With the pm 88 in case it is-desired to swing the shoe support forwardly without actuating nail carrier. The lever 90 is normally held inoperative position by a spring 92.

the use of the machine above described, assuming that the operations incident to heelinp, a shoe have been completed, he shoe support 2 is drawn forward by the perator to remove the heeled shoe. Near "he end of'the forward movement of the shoe support theclutch controlling lever actuated by-the tripping lever 76 to cause be imparted to the driven member 88. The nail carrier 25 is l by moved-into position over the nail and. afterward returned -to nail re- The outer end of the .occur while the shoe support and of the lever 76 the dog 80. yields,

= machine there is .ceiving position. It Will be understood that the movement of the nail carrier into nail delivering position is limited by a stop arranged upon the nail block head, as is dis closed in the patent above referred to. This movement of the nail carrier is arrested by said stop before the Wrist pin 64 passes the dead center, so that during the middle portion of the revolution of the driven member 38 the nail carrier is stationary. It Will be understood that at this point there occurs relative movement between the rod 66 and the pin 68, the spring 72 being compressed. his interval of time during which the nail carrier is stationary may be made of sutlicient extent to insure that the nails Will descend into the nail block. In the latter portion of the revolution of the driven member 38 the nail carrier is returned to its nail re ceiving position. It will be understood that in this position it is automatically supplied with nails from a suitable nail asserting apparatus. It will also be seen that, since the heel and top lift holder'is actuated in the movement of the nail carrier into nail delivering position, the movement of said holder into operative position is automati cally efiected and is'controlled by the movement of the shoe support.

he reciprocation of the nail carrier and the actuation of the heel and top lift holder is in its for- Ward position and prior to the actuation of the nail driving mechanism. It is desirable that the driving lever trolling lever 60 be so arranged that the clutch mechanism is actuated near the end ..of the forward movement of the shoe supated in adjusting the shoe in the machine is avoided.

The feature of supplying nails to the nail be understood that in that machine it is necessary to supply the nails to the nail block before inserting a heel and a top lift in their respective holders. In the use of mechanism embodying the present invention, not only is the necessity of performing a separate operation avoided, that of supplyiflig nails to the nail block, but inasmuch as t the close of the cycle of operations of the less liability or, the nail 76 and clutch 0011- I e nails are supplied to the nail block atclaim as new and desire to secure by Letters Patent of the United States is 1+- l 1.
